In 1997, the New York Yankees kicked John Wetteland to the curb for their young Panamanian set-up man, and have been spoiled rotten ever since.
This young hurler, Mariano Rivera, has saved 583 games (and counting) since then, and is pitching just as well in 2011 as he ever has.
Watching Mariano pitch throughout the course of a year is like watching a season of House: They both solve cases that seem impossible better than anybody else could imagine, and even when they screw up, you still somehow walk away impressed.
Still, while his pitching might fool you, Mo is 41 years old, and he may need to be replaced sooner than we think.
We see sudden drop-offs in the MLB all the time, and Mo's former and current teammates are a few of them.
Bernie Williams suddenly went from hitting .333 to .263 in just one season, Derek Jeter plummeted from .334 to .270 and Jorge Posada dipped from .285 to .248. These things happen.
Of course, a reliable bullpen is crucial for a good team that strives to be great, and Mariano has made that difference in five World Series champions.
But who's next in line?
Joba Chamberlain's unfathomable 2007 campaign made us think it was him, but he has struggled with consistency ever since.
Rafael Soriano and his ridiculous contract looked like a viable option, but he's been injured, and he isn't the youngest guy on the team himself.
Eventually Joe Girardi will have to turn to another name in his trusted binder to make the last three outs of a game.
Right now, it seems as though that name will be David Robertson.
Robertson is a great young reliever with all the tools a pitcher needs to close out games.
Let's take a look at what makes Robertson the prime candidate.
